Markets Surge as Nvidia Earnings Reignite the AI Rally. Stock Futures Soar.

Stock futures were surging Thursday after chip maker Nvidia issued strong revenue guidance for the current quarter, putting to bed any fears that the artificial-intelligence boom was about to fizzle out. S&P 500 futures added 1.3%, and contracts tied to the tech-heavy Nasdaq 100 jumped 1.7%. Nvidia beat analysts’ estimates for earnings and revenue and provided a January-quarter forecast that was well above Wall Street’s expectations, sending its shares up 5.1% in late trading.
